"I am going to create borders. No drugs are coming in. We're going to build a wall," Trump said

The appeal, made in a video posted to Facebook, comes three days before New Hampshire hosts the nation's first 2016 primary.

Washington (CNN)Donald Trump on Saturday again vowed to build a wall along the Mexico-U.S. border -- this time arguing that it would help stem New Hampshire's "drug epidemic."

The appeal, made in a video posted to Facebook, comes three days before New Hampshire hosts the nation's first 2016 primary.

"New Hampshire has a tremendous drug epidemic," Trump says. "I am going to create borders. No drugs are coming in. We're going to build a wall. You know what I'm talking about. You have confidence in me. Believe me, I will solve the problem."

"They will stop coming to New Hampshire. They will stop coming to our country," he added.

Trump has repeatedly said he will build a wall along the southern border of the United States to prevent undocumented immigrants from entering the country.

The businessman also said he will work to help people struggling with addiction.

"And the people that are in trouble, the people that are addicted, we're going to work with them and try and make them better. And we will make them better," Trump said.

According to an October 2015 survey from the University of New Hampshire and WMUR, a quarter of Granite Staters think drug abuse is the most important problem facing the state, the first time in eight years that a plurality think an issue is more important than jobs and the economy. The epidemic reaches across all demographics and nearly half of those surveyed say they know someone who has abused heroin.
